Struct Pick

pub(crate) struct Pick<'tcx> {
    pub item: AssocItem,
    pub kind: PickKind<'tcx>,
    pub import_ids: SmallVec<[LocalDefId; 1]>,
    pub autoderefs: usize,
    pub autoref_or_ptr_adjustment: Option<AutorefOrPtrAdjustment>,
    pub self_ty: Ty<'tcx>,
    unstable_candidates: Vec<(Candidate<'tcx>, Symbol)>,
    pub receiver_steps: Option<usize>,
}

Fields

item: AssocItem

kind: PickKind<'tcx>

import_ids: SmallVec<[LocalDefId; 1]>

autoderefs: usize

Indicates that the source expression should be autoderef’d N times

A = expr | *expr | **expr | ...

autoref_or_ptr_adjustment: Option<AutorefOrPtrAdjustment>

Indicates that we want to add an autoref (and maybe also unsize it), or if the receiver is *mut T, convert it to *const T.

self_ty: Ty<'tcx>

unstable_candidates: Vec<(Candidate<'tcx>, Symbol)>

Unstable candidates alongside the stable ones.

receiver_steps: Option<usize>

Number of jumps along the Receiver::Target chain we followed to identify this method. Used only for deshadowing errors. Only applies for inherent impls.

Implementations

impl<'tcx> Pick<'tcx>

pub(crate) fn differs_from(&self, other: &Self) -> bool

In case there were unstable name collisions, emit them as a lint. Checks whether two picks do not refer to the same trait item for the same Self type. Only useful for comparisons of picks in order to improve diagnostics. Do not use for type checking.

pub(crate) fn maybe_emit_unstable_name_collision_hint( &self, tcx: TyCtxt<'tcx>, span: Span, scope_expr_id: HirId, )

In case there were unstable name collisions, emit them as a lint.

Trait Implementations

impl<'tcx> Clone for Pick<'tcx>

fn clone(&self) -> Pick<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for Pick<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
